a few things to consider. your guitar is a 1/4" MONO out, your Mac is an 1/8" STEREO in. your sound is gonna be coming in only on one side into GB. i suggest you pickup a splitter cable, or ideally, a little mixer. a preamp wouldn't hurt either, unless your guitar has active pickups. you should take a trip to the local music store and tell them what you're looking to do.

I'm trying to find the cheapest way to get the guitar in the machine.

thanks!

Using a 1/4" to 1/8" adapter, the signal is weak, but not completely unuseable.

To get decent quality, you'll want some kind of pre-amp (Radio Shack should have a cheap, small mixer). Also, you'll want a long guitar cord if you have a CRT monitor. Having humbucking pickups help, but they aren't 100% in noise rejection.

what about a bluetooth plug? does one exist? i love my bluetooth mouse, keyboard, headset, phone etc. a guitar plug would be so cool to just strut around while garageband does its amp stuff and whatever else.

hahahhahahahaha...I'll have to look into that! I can throw some headphones, and strut all over my apartment doing my best impressions of Eddie Van Halen, Keith Richards, Pete Townshend et al. hahhahaha

I got the little Radioshack adapter. It works ok--you could get pretty acceptable results using this. I also tried putting some effects pedals in between the guitar and the computer--my Ibanez Tube Screamer made for a pretty good sound.

I got a Radio Shack adapter that has a 1/4" mono plug for my guitar and a 1/8" stereo jack, and bought a 16' shielded cable with 1/8" stereo plugs on each end. That way I don't have a heavy guitar cord to drag around and plug into the rather fragile jack on my PB. All for under $15, and it works great.

Plug in headphones, launch the freeware app LineIn, and my PB is now my practice amp as well!
